Ongoing since 09:30 PM UTC, affecting New app builder.
Some customers report that Norton, AVG, and other safe browsing vendors are flagging retool.app as dangerous and blocking it. Affected users may see a “dangerous webpage” warning or be unable to load published Retool apps or the app builder preview. Retool services are operating normally. We believe the block comes from how these products classify the domain. We are submitting reclassification requests to each vendor and following up with them. If your IT team manages these products, they may be able to add an exception for *.retool.app.
